This is already a known issue with assisted reproduction, the number of Musklets is probably into three figures by now. If he's paying women to be surrogates somehow this makes him less unethical than most of the guys who do this.
He could also have a deal with one of the numerous unregulated sperm banks out there (for real it's a libertarian fantasyland) to be the sole source for the $50 discount straw specials they run. If that's the case the number could easily be into the thousands. Utterly horrifying to contemplate.
I popped in the target range (shaded box) and typical levels over the course of a menstrual cycle and yes, it is a little bit on the low side of the target range. 2 patches gets you into the target range.
